The book of Colossians is the third book in the group of Paul's epistles (Eph., Phil., and Col.), which speak of Christ and His Church. The focus of the Colossian letter is the truth that Christ is the Head of the church, which is His body. The Colossians saints were being subjected to false teaching that did not uphold Christ as our Head and did not hold fast to Him as our Head. In answering these false teachers, Paul declares and expounds on two doctrines about Christ: 1) the superiority of Christ - that He is very God, and 2) the sufficiency of Christ's death and resurrection - that it was enough to pay for our sins in full and give us eternal life. If we are to truly know Christ, we must see that He is our life.
